To all whom it may concern.'

Be it 4known that I, LoUIs F. GEILs, a i

citizen of the United States, residing at Chicago,in the county 'of Cook and State of Illinois, have invent-edcertain new and useful Improvements in Headlight Deflectors; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which' it appertains to make and use the same.

The present invention relates to a light deflector for use in the head lamps of motor vehicles, and aims to provide a novel and improved delector to be associated with an electric lamp bulb to reflect the light rays so as to avoid the upward reflection of the light rays by the .reflector above a substantially horizontal plane, it being the function of the device* to keep the light down on the road without blinding persons in front.

It is an object of the invention to provide a simple deflector for a lamp bulb of novel and -improved formz forde'llecting such light rays as ordinarily produce the objectionable glare above the focal axis or horizontalV lane of the lamp, and in order that the re ected rays will be reflected forwardly and downwardly by the reflector o f the lamp. l

Another object is the provision of novel means for holding the def'lector in place' on the lamp bulb, and enabling the dellector to be applied to lamp bulbs of differentv sizes or diameters, the device being such that the parts are held under spring influence to eliminate vibration or loosenessv as well as preventing displacement of the deflector.

IVith the foregoing and other objects in view, which will be apparent as the description proceeds, the invention resides in the construction and arrangement of parts, as hereinafter described and claimed, it being understood that changes can be'made within' the scope of what is claimed without departing. from the spirit of the,invention.

The invention is illustrated in the accompanying drawing, wherein- Figure 1 is a side elevation of the deflector applied to alamp bulb, showing the reflector and lens of the lamp in vertical section.

Fig. -2 is a front View of the defiector'.

Fig. 3 is a rearview of the device.

Fig. lis a vertical section of the'deflector on the line 4-4 of Figx.

Fig. 5 is a horizontal section on the line 5-5 ofFi 3. p

The delgector proper is composed of a shield or screen 7 stamped or pressed from suitable sheet metal, and disposed in a vertical plane across the front of the electric lamp ,bulb 8 within the reflector S).` The shie d 7 is-fornied with a forwardly bulged portion lO'forming a recess to snugly receive the forward portion of the bulb 8, and said shield has an aperture 11 centrally of the portion 10, permitting some light rays to/pass directly forward through said aperture along the focal axis of the lamp.

The detleetor also includes a Aspoon 18, also stamped or pressed from sheet metal. extending rearwardly from the lower curved edge of the shield 7 below the portion l0, and said spoon is concaved transversely so as to be disposed closely under the bulb 8. The lower curved edge of the shield 7 has lugs or ears 14 extending through slots in the forward end portion of the spoon 13 and bent or clinched against said spoon, for securing the spoon to the shield.

The rear face of the shield 7 and upper or inner surface of the spoon 13 vare polished, plated or otherwise finished so as to reflect the light rays, the shield 7 reflecting the light rays rearwardly and upwardly, and the spoon 13 reflecting the light rays upwardly from the source of light. The light rays are prevented, by the vshield 7, from passing directly forward from the lamp bulb through the lens of the lamp, and the spoon 13 prevents the light rays from passing from the lamp bulb to the lower portion of the reflector 9, so as to prevent such light rays from being reflected by the lower portion of the reflector 9 forwardly and upwardly. The light rays Which are reflected rearwardly and upwardly by the deflector are reflected forwardly and downwardly by the upper portion of the reflector 9 thus keeping the light on-the road and preventing objectionable glare.

The deflector is holdip the d rovided with means'for itself in p ace on the bulb. Thus, ector Yproper has the arms 15 extending rearwardly from its opposite side edges,

above the spoon or portion 13, and at the opposite sides of the portion 10, and said arms are integral with the sheet metal deflector. A clasp or retaining member 16 is provided, bein bent from wire as shown, and said clasp as the forwardly extending terminals or arms 17 slidably overlapping the arms 15. Coiled springs 18 surround the arms and 17, and theends of the arms 15 are split and-have portions 19 bent in opposite directions to provide seats for the springs 18, while the ends of the arms 17 are engaged, as at 19', with the forward ends of the s rings. rllhe springsin expanding will slide the clasp 16 and delector toward one another, and they caribe separated, which will compress the Springs, thereby enabling the device to be applied to lamp bulbs of different sizes.

The clasp 16 has the portions 20 converg ing from the arms 17 and connected by a. resilient loop or split band 21, and the loop or band 21 is adapted to be snapped around the plug 22 of the bulb 8, so as to embrace said plug in rear of the bulb 8. In applying the loop or band 21 of the clasp on the plu 22 behind the bulb 8 and moving the shie d 7 upwardly in front of the bulb, the springs 18 are compressed, by the separation of the claspand shield, so that the clasp and shield are held under spring influence against the back and front, respectively, of the bulb. rIhis will not only hold the device in position on the bulb but will also prevent the device from` rattling or becoming loose.

rIhe upper portion of the shield 7, above the portion 10 which bears a ainst the lamp bulb, has concentric arcuate ouver portions 23 struck forwardly therefrom, and extendf at an angle forwardly and inwardly' ing , -toward the focal axis, and providing arcuate slots 24 in the shield through which the light rays can pass. The portions 23 prevent the light rays from passing directly forward-through the slots, and reflect the light rays forwardly and downwardly. The light rays can thus pass through the shield but are required to pass downwardly through the shield so as not to pass from the lamp above the focal axisl or horizontal plane of the lamp. At suitable points, the shield 7 has webs 25 between the adjacent ends of the louver portions 23, for purpose of strength.

` The device can be used on the bulb with different kinds of lenses, and the device is complete in itself to effectively hold the light down and prevent objectionable glare, it only being necessary to apply the device to the lamp bulb.

to snap around and embrace' the plug of' the bulb behind the bulb, said clasp having forwardly extending arms in sliding overlapping engagement with the aforesaid arms, and coiled springs surrounding said arms and engaging them for moving the clasp and shield toward one another to hold the shield against the bulb.

2. A light deiector comprising a shield to be disposed in front of and to bear against a lamp bulb, a clasp having a loop to snap around the plug of the bulb from one side thereof and to embrace said plug behind the bulb, said shield and clasp having slidably overlapping arms, and spring means associated with said armsfor moving said clasp and shield toward one another to hold the shield against the bulb.

3. A light deiector comprising a shield having a portion to bear against a lamp bulb at the front thereof with the shield projecting .upwardly from the bulb, a rciector portion extending rearwardly from the shield to be disposed below the bulb for reflecting the light upwardly, the shield having slots above said tirstnamed portion and louver portions adjacent to said slots so arranged that the light rays must pass forwardly and downwardly through said slots, and means connected to the shield and engageable behind said bulb and including springs for holding the firstnamed portion against the bulb.

4. A light deflector comprising a shield having a portion to be disposed in front of and to bear against a lamp bulb with the shield extending upwardly from said bulb, a reflector portion extending rearwardly from the shield to be disposed below the bulb for reflecting the light rays upwardly, the shield having slots above said portion of the shield and louver portions adjacent to said slots and so arranged that the light rays must pass forwardly and downwardly through said slots, a clasp to engage around the plug of the bulb behind the bulb, and spring means connecting said shield and clasp for holding the shield against the bulb.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
